- Side-actuated with an included square-drive key means that this unit can accommodate parts with blind bores.
- Precision-ground square and concentric within 0.0005". If higher accuracy is needed the mandrel can be clocked-in once the unit is gripped in a chuck.
- Universal straight shank mount enables this ID workholding system to be easily moved from machine to machine as jobs require.
